What are the options for
common timeframes?

3.
Why common timeframes are important and
needed?
Periodicity and effectiveness: the Paris Agreement’s Architecture is based on
elements with a certain periodicity such as the GST and the communication of
NDCs (every 5 years). To ensure the proper functioning of this architecture, the
implementation timing of NDCs must be consistent with that periodicity.
Achieving consistency is crucial to ensure the provision of a timely, comparable and
objective frame of reference (as a result of periodic collective review of efforts) to
indicate all Parties how subsequent action under the Agreement should be updated
or enhanced, in a nationally determined manner.
Also, it reduces the risk of free-riders and of locking-in a level of ambition that fails
to deliver on the required trajectories to achieve the Agreements long – term goals.

4.
Options
5 years 10 years
Consistent with timeframes of
some important elements of the
ambition mechanism (i.e. GST).
More chance of making technical
and fundamental adjustments
(even on the level of ambition)
without undermining transparency
and consistency of tracking the
progress in the implementing
NDCs.
More time to prepare and conduct
a consultation process necessary to
approve and communicatethe
subsequent NDCs.
Many challenges for the national
process of formulation and
implementation of NDC
Higher probability of locking-in a
low level of ambition
Lag between communication and
the implementation period will be
increasingly larger.

• Some parties are concerned about challenges of having a short NDC
implementation period but it is important to bear in mind that:
• We are not going to formulate subsequent NDCs from scratch.
• The process of preparing new NDCs will be a continuous process
based on the experience and capacities acquired by the Parties.
• Even the consultation process to national actors should not be as
cumbersome as it was the first time.
• Using long term goals under low carbon development strategies as
a reference could facilitate the formulation process of the NDCs.

7.
5 YEARS TIMEFRAME COULD BE A MORE SUITABLE OPTION…

8.
A FINAL MESSAGE…
• It is necessary that the CMA consider the common time frames in
light of what is needed to deliver the collective goals under the Paris
Agreement instead of having discussions based on what we did in the
past.
